Brain waves can cut braking distances, researchers say

Tapping into drivers' brain signals can cut braking distances and avoid car crashes, according to scientists. Researchers at the Berlin Institute for Technology attached electrodes to the scalps of volunteers inside a driving simulator.

The system detected the intention to brake, and cut more than 3m (10ft) off stopping distances, the team report in the Journal of Neural Engineering. The team's next aim is to check the system in a series of road tests.
